Weights & Measures

The Weights & Measures Division supervises all sales of commodities within the City of Green Bay and also provides weights and measures services to the Villages of Allouez, Bellevue, and Howard.  This is regulated by Chapter 22 of the City code.

What we do

The City regulates sales or purchases done by weight or measure and also tests and certifies scales, scanners, meters, and measures used within the City.

Staff checks weight/measure of factory and store packed products, enforces labeling rules on packaged products, and investigates and resolves consumer complaints, taking enforcement action where necessary.

In addition, the City Sealer approves City licenses for transient merchants, solicitors, salvage, provides testing services to area governmental agencies, and provides consulting and certification services to area industries.

Concerns regarding any of these items can be addressed by filling out an Online Report or by contacting the Weights & Measures Division by telephone at (920) 448-3300

The City Sealer has been asked to expand inspections to protect consumers who use credit cards to buy gasoline or other motor fuels due to the increased use of skimmers.

Skimmers are illegal devices that can copy the electronic data encoded into a credit card.  Criminals who commit identity theft use that data to make counterfeit credit cards or to make electronic purchases without the victim’s knowledge.

Some devices are placed on the outside of a credit card reader.  Some are portable devices that can be used to capture data when a restaurant server takes possession of a credit card to collect payment for a meal.  And some can be installed inside a retail-fueling device to capture data whenever a credit card is used to purchase gasoline.

Such devices were reported in Arizona, Florida, and even Milwaukee in recent months.  Many service station owners have implemented their own security measures to protect their customers.

If evidence of illegal activity is found, the City Sealer will immediately notify police and the U.S. Secret Service, which investigates allegations of identity theft.

Avoid Victimization by Credit Card Skimmers

Anyone who uses a credit card can fall victim to a “skimmer” if they’re not careful.  While our City Sealer is taking steps to combat skimmers on fueling devices, they can be installed on any device that is used for a credit or debit card transaction.

Here are some steps that a careful consumer should consider:

  • While the vast majority of restaurants take steps to protect their customers, some credit card thieves recruit restaurant servers who secretly record your credit card data when you charge a meal.  Whenever possible, consider bringing the check to the cashier yourself.
  • Check your credit card statements regularly and report any discrepancies immediately.  The Truth-in-Lending Act limits consumer liability to $50 once a credit card is reported lost or stolen.  Some issuers may waive the $50 fee.
  • Debit cards fall under a different law – the Electronic Fund Transfer Act.  Liability is limited to $50 if you notify your financial institution within 2 business days of discovering that your debit card was lost or stolen.  If you wait more than 2 business days, but notify your bank within 60 days of the date your statement is mailed, you could lose up to $500.  Wait longer than that, and you could lose all the money in your account.
  • If someone used your credit without your knowledge, contact the companies in question.  Be sure to put complaints in writing.
  • Also contact the three major credit bureaus:  Equifax at (800) 525-6285, Experian at (888) 397-3742, and Trans Union at (800) 680-7289 if you discover fraudulent activity.
  • Contact the Federal Trade Commission at (877) 438-4338.  While federal investigators only tend to pursue larger, more sophisticated fraud cases, they do monitor identity theft crimes of all levels with the hope of discovering patterns and breaking up larger rings.  Fill out the ID Theft Affidavit at the FTC’s website, make copies, and send to creditors.  The agency also has an online complaint form.
  • Alert the police.  Fill out a police report and consider signing a written affidavit verifying that unauthorized transactions on your account are fraudulent.  Send copies to creditors and credit bureaus as proof of the crime.

Most skimmers don’t capture PIN numbers.  Whenever possible, use a card that requires a pin number.


  1. Fill up your car or truck in the morning when the temperature is still cool.  Remember that all service stations have their storage tanks buried below ground; the colder the ground, the denser the gasoline.  When it gets warmer, gasoline expands.  If you’re filling up in the afternoon or in the evening, a gallon is not exactly a gallon.  In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol, and other petroleum products) are significant.  Every truckload is temperature-compensated so that the indicated gallon gauge is actually the amount pumped.  A one-degree rise in temperature is a big deal for businesses, but service stations don’t have temperature compensation at their pumps.
  2. If a tanker truck is filling the station’s tank at the time you want to buy gas, do not fill up.  More than likely, dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car’s tank.
  3. Fill up when your gas tank is half-full (or half-empty) because the more gas you have in your tank, the less air there is.  Gasoline evaporates rapidly, especially when it’s warm.  (Gasoline storage tanks have an internal floating “roof” membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation.)
  4. If you look at the trigger, you’ll see that it has three delivery settings:  slow, medium, and high.  When you’re filling up, do not squeeze the trigger of the nozzle to the high setting.  You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping.  Hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains more vapors, which is being sucked back into the underground tank, so you’re getting less gas for your money.

We hope this will help ease your “pain at the pump”.
